Traditional Chinese medicine has a wide range of contraindications, including contraindications for compatibility, pregnancy, consumption, medical conditions, and formulations.
1. Contraindications for Compatibility
Contraindications for compatibility refer to the prohibition or unsuitability of certain drugs being used together in a compound. As early as in the "Seven Emotions" section of "Classic of the Materia Medica," it is stated that "do not use drugs that are incompatible or antagonistic," which serves as the basic basis for contraindications for compatibility in later generations. However, the consequences of incompatibility and antagonism are different. Incompatibility only reduces the efficacy of certain drugs, and some drugs can reduce their side effects by decreasing certain properties, making it beneficial for the medical condition. Therefore, it is not an absolute contraindication. On the other hand, antagonistic compatibility may harm the patient's health and even endanger their life. Therefore, drugs with antagonistic properties should generally be prohibited from being used together. Han Bao, a physician from the Later Shu Kingdom in the Five Dynasties period,
